The COVID-19 pandemic has not just gently nudged but forcefully thrust environmental issues into the forefront of public consciousness. This shift in awareness has been a long-time aspiration of conservation scientists, who have played a crucial role in advocating for recognizing nature’s contributions to human life and a healthy environment. I explain the advantages of using newly available tools and sources of digital data, i.e., the absolute search volume in Google using the flag keywords biodiversity, climate change, and sustainability, Τhe GDELT Project, which monitors the world’s broadcast, print, and web news, and the difference-in-differences method comparing paired samples of public interest before and after the pandemic outbreak. We focus on the case of UK citizens’ public interest. Public interest in the flag keywords in the UK showed a highly significant increase during the pandemic. The results contradict hypotheses or findings presented elsewhere that the public interest is attenuated during and because of the public health crisis. I support growing public awareness of the existential risks springing from human materialism misappropriating nature, environment, and resources. In conclusion, I advocate for a “new conservation narrative” that could be fostered by the increased public interest in environmental topics during the pandemic. Full article

The consumption of contaminated water contributes to the global burden of diarrhea and other water-borne diseases, especially among young children. While decentralized solar water disinfection treatment systems (hereafter SODIS) remain a viable option to have safe drinking water, our understanding of the effects of household water treatment before use on willingness to accept and adopt a SODIS is limited. In this study, a complementary log-log regression analysis of the compositional and contextual factors that systematically vary with willingness to accept and adopt a SODIS in the Sawla-Tuna-Kalba (STK) district of Ghana was carried out. Based on our findings, a greater proportion of households (97%) are willing to accept and adopt a SODIS. Compositional and contextual factors such as age, marital status, education, religion, and geographical location significantly contribute to households’ willingness to accept and adopt a SODIS in the STK district of Ghana. Households that treat their water before use (66%, p < 0.05) are more likely to accept and adopt a SODIS compared to those that do not treat their water before use. The findings, therefore, suggest that scaling up SODIS in the STK district is sacrosanct and highlight the necessity to analyse compositional and contextual factors influencing willingness to accept and adopt SODIS. Our findings will inform policies and programs aimed at implementing SODIS in the study area to improve the health of communities that rely on poor-quality drinking water sources. Full article

Sustainable initiatives play a crucial role in promoting digital health equity by addressing barriers to access and ensuring equitable use of digital health technologies and services. These initiatives may arise in various contexts, including local collaborative networks that emerge in the municipal context. This study aims to identify and characterize the municipal initiatives that have been developed in Portugal to promote digital health equity. It adopts a mixed methods approach to initially quantify the distribution of these projects in the Portuguese territory and, at a later stage, to understand the level of influence of these projects, considering their impact on individual, interpersonal, community, and societal levels. The findings identified 22 municipal sustainable initiatives and concluded that there is a strong relationship between the areas of community and individual influence. The results of this study are relevant to deepening the knowledge of bottom-up innovation in the digital health field and establishing public policies to increase the impact of these projects at the territorial level, the communities involved, and the social objectives addressed, contributing to greater social cohesion.

This study critically investigates the socio-economic effects of urban expansion and forced relocation on peri-urban communities in Nkurenkuru, Namibia. Urban expansion in middle-income countries often has negative impacts on peri-urban and rural communities. Urban expansion leads to the displacement of such communities, and this study focuses on the socio-economic effects of such urbanization-induced displacement. This study used a qualitative research design, with in-depth interviews to chart the effects of relocation on community life and livelihoods. Findings reveal that before relocation, community members were involved in several land-use-related socio-economic activities. Relocation has worsened their living conditions with a significant drop in household income, financial stability, food security, and their access to vital services. Other findings include insufficient support from municipalities during the relocation process. This study shows the socio-economic repercussions of relocation and the importance of community consultations and participation in the urban expansion process. Full article

Since the 1970s, the issue of ageing farmers and generational renewal in agriculture has consistently attracted the attention of policymakers. However, despite successive reforms of the European Union Structural Funds, efforts to encourage young people to enter the agricultural sector remain largely focused on agricultural and rural policies, specifically on the First Settlement scheme. This paper highlights the role of the European Union’s rural development policy in supporting and encouraging generational renewal in agriculture. A qualitative analysis of the Italian case examining some of the demographic changes that have occurred within the agricultural system at the regional level has been conducted. The analysis is based on the comparison of policy implementations in different programming periods. Using data from the General Censuses of Agriculture and the Italian Agricultural Payments Agency—supplemented by the Annual Implementation Reports of the Italian Rural Development Programmes—the research traces the evolution of initiatives supporting young farmers. The main findings reveal a notable decline in the number of young people in the primary sector over the last decade, together with an ageing population of agricultural farmers. Measures to support young farmers under the Common Agricultural Policy appear to be ineffective in countering the ageing trend. There is scope for integrated policies to enhance the attractiveness and profitability of rural areas and to ensure long-term sustainable generational renewal in the agricultural sector.

Pakistan’s economic growth has been hindered by various internal and external factors since its independence in 1947. This study aims to identify the root causes of these issues and provide a comprehensive understanding of the country’s economic situation. Internally, inefficient bureaucracy, corruption, inadequate support for small and medium enterprises (SMEs), labor market rigidity, tax evasion, and regional inequalities have impeded development. External factors such as political instability, terrorism, weak governance, foreign policy challenges, and insufficient infrastructure have discouraged investment and disrupted economic activities. Pakistan’s reliance on low-tech exports has also led to a loss of competitiveness in international trade. To revitalize the economy, the study suggests reforms in governance, bureaucracy, and infrastructure, with a focus on supporting SMEs, reducing corruption, and attracting investment. The adoption of circular economy (CE) practices, particularly through the use of recycled materials, is proposed as a viable pathway to enhance economic resilience and environmental sustainability. The study highlights the potential for integrating CE strategies, drawing from successful global practices, to address Pakistan’s economic and environmental challenges. However, the reliance on historical data and linear econometric models may not fully capture the evolving economic dynamics, necessitating further research incorporating real-time data and sector-specific approaches. Despite these limitations, the study provides actionable insights for policymakers, offering a framework for Pakistan and other developing economies to achieve sustainable growth. Full article

The complexity of urban areas has motivated the search for integrative approaches. This paper addresses three topics—human habitat, urban metabolism, and urban entropy—to explore their links within the context of urban territory and sustainability. The lack of approaches, outlooks, and synergies motivates the search for an integrated conceptual framework, what I originated as a review of published works to contribute an interdisciplinary and multiscale outlook. From reviewing 41 articles, published from 1960 to 2020, definitions were extracted, original concepts were identified, synthetic definitions were formulated, and basic elements were identified to be integrated into a first synthetic approach, both illustrative and schematic. Eighteen binding key concepts, which were derived from 83 definitions, were incorporated into the proposed conceptual framework. We suggest that the human habitat, urban metabolism, and urban entropy are strongly interrelated, confirming the utility of the proposed conceptual framework and showing the potential to generate methodological approaches that integrate one or several conceptual elements that comprise it. Demonstrating the explicit bond between definitions, concepts, and components integrated systematically into the proposed conceptual framework is innovative in the field of scientific investigation, considering its applicability to public policy, resource management, or sustainable urban planning.

Environmental degradation driven by human activities has heightened the need for sustainable development strategies that balance economic growth with ecological preservation. This study uses a compartmental model approach to examine the effects of global warming on ecosystem dynamics, focusing on how rising temperatures alter interactions across trophic levels. Three case studies of varying complexity, including a human ecosystem incorporating social and economic factors, were analyzed by integrating feedback loops between greenhouse gas emissions, temperature anomalies, and ecosystem responses. The results quantitatively demonstrate that even minor disruptions in one part of an ecosystem can cause significant instability across trophic levels, potentially driving the system to collapse in a short period. These findings from all case studies highlight the cascading impacts of global warming, underscoring the intricate relationship between climate change and ecosystem stability. Furthermore, this study offers qualitative insights into the potential consequences of climate change on biodiversity and resource availability in real ecosystems, highlighting the vulnerability of such systems and the importance of incorporating feedback mechanisms into environmental policy and decision-making processes. The approach employed in this study offers a more robust framework for understanding ecosystem responses and for developing strategies to enhance resilience against climate change, thereby protecting the long-term sustainability of ecosystems.

Since proclaiming independence in 1960, Senegal has faced economic and demographic imbalances across its regions. To address these disparities, the government launched decentralization policies in three major phases, aiming to stimulate socio-economic growth at the local level. This study examines the impact of these policies on urban–rural development using socio-economic data between 2000 and 2020, and a multiple linear regression model in the entirety of Senegal. The findings reveal significant correlations between rural population growth, access to electricity, fertilizer availability, and per capita cultivated land, all positively associated with agricultural productivity. Additionally, rapid urbanization (47.3%) and weak land tenure (88.6%) adversely affect ecological systems and contribute to the proliferation of slums. A notable lack of health facilities per capita highlights a severe gap in healthcare accessibility. The study suggests increasing agricultural income, creating jobs, and promoting policies that support rural collective entrepreneurship as critical steps. It also recommends adopting a “one ecological zone, one economic activity” strategy to reduce economic disparities and encourage sustainable development in rural Senegal. Full article

Rapid urbanization in South Asian cities has triggered significant changes in land use and land cover (LULC), degrading natural biophysical components and intensifying urban heat islands (UHIs). This study investigated the impact of LULC changes on land surface temperature (LST) and the role of biophysical indicators in enhancing urban resilience to thermal extremes. We used Landsat satellite imageries from 1993 to 2023, conducted a comprehensive analysis of LULC changes, and estimated LST variations at 6-year intervals in the Dhaka, Gazipur, and Narayanganj districts in Bangladesh. Afterward, we performed statistical analysis upon employing correlation, regression, and principal component analysis (PCA) techniques to summarize information. The results reveal that 339.13 km² worth of urban expansion has occurred in last 30 years, with an average annual growth rate of 3.5%, accompanied by a substantial reduction in water bodies (−139.17 km²) and vegetation cover. Consequently, summer temperatures exceeded approximately 36.52 °C in dense urban areas. Also, the results highlighted the strong influence of built-up areas (BSI and SAVI) on LST, while vegetation (NDVI) and water indices (NDWI) exhibited a negative association. The findings emphasize the urgency of integrating green infrastructure and deploying sustainable urban planning policies to mitigate the potential adverse impacts of scattered urbanization in the face of climate change.

The integration of sustainable practices in tourism is increasingly critical, given the sector’s substantial environmental and social impacts. Although the need for innovation management to promote sustainable tourism is widely recognized, various barriers hinder its effective implementation. This study employs the Decision-Making Trial and Evaluation Laboratory (DEMATEL) methodology to systematically examine these barriers, identifying their interconnections and assessing their broader implications. The findings indicate that a short-term focus and financial constraints are the primary effect barriers to implementing innovation management in sustainable tourism. Their prominence as endpoints in the flow of impact within the model of interconnected barriers developed in this study underscores the need to further address the deeper, cause-related barriers that propagate these effects, such as inadequate leadership support, resistance to change, poor stakeholder communication and collaboration, insufficient knowledge and skills, and restrictive regulatory policies. Additionally, industry-specific challenges like a fragmented industry structure and fluctuating market conditions exacerbate these difficulties. Therefore, a comprehensive, holistic approach is essential for transitioning the tourism sector towards sustainable practices through innovation management and overcoming inherent financial and strategic barriers. This study advocates adopting the recently published Management System Standard ISO 56001:2024 as a structured innovation management framework capable of systematically and holistically mitigating these barriers. By analyzing the cause-and-effect relationships among the identified barriers, this study ultimately provides valuable insights that aid stakeholders—including policymakers, business leaders, and community representatives—in devising more effective, inclusive, and forward-thinking approaches to innovation in sustainable tourism. This is crucial for fostering a tourism sector that is not only economically beneficial but also environmentally responsible and socially equitable. Full article

In the Ugandan curriculum, theoretical teaching predominates in conveying water-related topics due to its efficiency and low resource requirements. However, this teacher-centred approach limits student interaction and collaborative learning. Conversely, game-based learning can enhance social skills, critical thinking, and engagement, yet it remains underutilised in Ugandan education. To address this gap, this study developed three educational games: Water Conservation Snakes and Ladders (WCSL), Water Awareness Quartet Cards (WAQC), and Water Pollution Puzzle (WPP). These games were implemented in four schools—three primary and one secondary—where students engaged in competitive, team-based play. The impact of these games on learning outcomes was assessed through pre- and post-test questionnaires. Descriptive and thematic analysis indicated a significant positive effect, with WAQC showing a 25% greater influence on performance than WCSL (18%) and WPP (14%). The findings also underscored the importance of age in determining game acceptability and enjoyment. To enhance education on water-related issues, it is recommended that these topics be integrated into both Science and Social Studies curricula and taught consistently across academic terms. Ultimately, the Ugandan government should consider incorporating game-based learning strategies into schools to improve student engagement and learning in water resource management. Full article

Social media platforms, such as Twitter (X), have a critical role in disseminating health information. The study aims to highlight the potential of Twitter (X) as an influential tool for health communication, in addition to providing findings related to public health communication strategies in Ghana. The study investigated the role of Twitter (X) as a platform for building interactive health communication between the health communication system and citizens in Ghana during the COVID-19 pandemic of 2020–2022. Additionally, it has the potential to contribute to building dialogical health communication. The study analyzed a sample of COVID-19-related tweets from the official Ghana Health Service Twitter (X) account @_GHS from 2020 to 2022. The results showed that Twitter (X) was a key tool for health communication during the COVID-19 pandemic in Ghana, with both health institutions and the public sharing large amounts of health information. Furthermore, the study found evidence of dialogic communication, in which healthcare institutions and professionals are actively engaging with the public on Twitter (X). It concluded that public health communication on Twitter (X) has changed over time, as well as that the interactive health communication between the health communication system and citizens in Ghana was affected positively during the COVID-19 outbreak. It highlighted Twitter (X)’s potential as a tool for establishing a dialogue loop and building dialogic health communication. The results showed that before COVID-19, Ghana did not use Twitter (X) effectively to communicate with citizens about health matters. Twitter (X), with its wide reach and highly interactive nature through features such as retweets, has become a major platform for interactions facilitating dialogue between health institutions and health professionals and facilitating dialogue in public spaces surrounding health issues like COVID-19.

Objective: This study aimed to assess the impact of water quality as determined by its physical, chemical, and biological composition collected from five distinct points in Maragheh, Iran, on the performance and carcass traits of Ross-308 commercial broilers (mix of male and female) during the grower (11–24 days) and finisher (25–42 days) periods. Materials and methods: A total of 240 broilers were involved in the study, divided into five treatments with four replicates and 12 birds per replicate. In this study, a randomized design was used. Water samples were collected from five different points, and broilers were provided with these water sources during the grower and finisher periods. Water samples for testing were prepared from the water wells of the meat poultry farms located in the northern, eastern, western, and southern lands, and the experimental farm, using hygienic and scientific methods. Performance parameters, including body weight, feed conversion ratio (FCR), and water intake, were measured. Results: During the grower period, no significant effects on performance and water intake were observed across the different water sources (p > 0.05). However, in the finisher period, significant differences were noted (p ≥ 0.05). The use of water from point A (control group) led to reduced water consumption, body weight, and increased FCR (p < 0.05). The northern water source exhibited the optimum FCR during the finisher period (p < 0.05). Throughout the entire experimental period, the water source significantly influenced broiler performance, with the northern water source (point B) corresponding with the highest weight gain and production index with the least feed intake (p < 0.05). Despite these variations, no significant changes were observed in the broilers’ carcass traits across different water sources (p ≥ 0.05). Conclusions: In conclusion, the study revealed that various drinking water sources, while not significantly impacting carcass quality traits, exerted notable effects on broilers’ performance. The northern water source emerged as particularly favorable, demonstrating superior weight gain and a production index with efficient feed utilization. These findings underscore the importance of water quality in poultry management, particularly during the finisher period, and highlight its potential influence on broiler performance. Full article

Sub-national governments (SNGs) in developing countries have increasingly explored green municipal bonds as a financing tool, driven by promises of lower borrowing costs, enhanced reputation, and support for sustainable economic development. This study aims to critically examine these claims by analysing the actual costs and complexities associated with green municipal bonds (GMBs). The research involves a comparative analysis of traditional municipal bonds and GMBs, focusing on the financial and operational challenges faced by SNGs. Detailed case studies from Mexico City and Cape Town are used to illustrate the practical implications of issuing GMBs. The findings reveal that, despite similar or slightly lower interest rates, GMBs often entail higher issuance costs due to the need for certification, monitoring, and reporting of green projects. These additional costs, coupled with the necessity of hiring external consultants, make GMBs more expensive and difficult to replicate after initial transactions. Furthermore, the study highlights that the demand from investors has not met initial expectations. While green-aligned investors show a higher appetite for GMBs, they constitute only a small portion of the finance market. Traditional investors, primarily focused on financial returns, are less inclined to invest in GMBs solely based on their green label. Consequently, many SNGs are increasingly turning to traditional “vanilla” municipal bonds as a more viable option for financing green initiatives. This shift underscores the practical challenges of GMB issuance in developing countries and calls for a strategic approach to balance the use of GMBs with other financing options to promote sustainable economic development.

Using the bibliometric software VOSviewer^® version 1.6.20 and Scopus as a bibliographic database, this paper aims to investigate the research streams in terms of the co-occurrence network of authors, terms extracted from the title field, countries, keywords, and organizations researching on IM from publications between 1974 and 2024. Retrieved from Scopus and using science mapping bibliometric techniques with VOSviewer^®, 4756 documents published on IM from 1974 to 2024 were analyzed, divided in three phases (1974–1995, 1996–2019, and 2020–2024), and limited to BMA (Business, Management, and Accounting), EEF (Economics, Econometrics, and Finance), and SOC (Social Sciences). The main findings are as follows: (a) there is a tendency for a minimal relationship between authors from different organizations and countries to collaborate in research on IM; (b) almost half (45.12%) of the publications on IM were published by authors from the European Union, which rises to 55.24% in Europe if the United Kingdom is included. These results are far ahead of those of the United States (13.4%), China (7.6%), the Russian Federation (3.6%), and Japan (2.3%). (c) While the first publications on IM deal with aspects related to product development, management, technology, R&D, and competition, there is a recent trend to link IM to sustainable development, open innovation, ecosystems, stakeholders’ engagement, and entrepreneurship.

To address the current challenge of climate change at the local and global levels, this article discusses a few important water resources engineering topics, such as estimating the energy dissipation of flowing waters over hilly areas through the provision of regulated stepped channels, predicting the removal of silt deposition in the irrigation canal, and predicting groundwater level. Artificial intelligence (AI) in water resource engineering is now one of the most active study topics. As a result, multiple AI tools such as Random Forest (RF), Random Tree (RT), M5P (M5 model trees), M5Rules, Feed-Forward Neural Networks (FFNNs), Gradient Boosting Machine (GBM), Adaptive Boosting (AdaBoost), and Support Vector Machines kernel-based model (SVM-Pearson VII Universal Kernel, Radial Basis Function) are tested in the present study using various combinations of datasets. However, in various circumstances, including predicting energy dissipation of stepped channels and silt deposition in rivers, AI techniques outperformed the traditional approach in the literature. Out of all the models, the GBM model performed better than other AI tools in both the field of energy dissipation of stepped channels with a coefficient of determination (R²) of 0.998, root mean square error (RMSE) of 0.00182, and mean absolute error (MAE) of 0.0016 and sediment trapping efficiency of vortex tube ejector with an R² of 0.997, RMSE of 0.769, and MAE of 0.531 during testing. On the other hand, the AI technique could not adequately understand the diversity in groundwater level datasets using field data from various stations. According to the current study, the AI tool works well in some fields of water resource engineering, but it has difficulty in other domains in capturing the diversity of datasets. Full article

Sheep breeding is one of the most important economic activities in Ahar City, Iran. However, due to traditional production techniques, livestock farmers face the problem of low productivity. To address this issue, traditional breeds can be replaced with improved and high-yielding ones; in the first stage, this requires the acceptance of these new sheep breeds by the region’s ranchers. This research aimed to evaluate the attitudes of the livestock breeders of Ahar City towards the improved breeds of sheep and the influential factors. We collected data through in-person interviews using a simple random sampling method, surveying 100 sheep breeders in Ahar. The breeders were categorized into three groups based on their attitudes towards improved breeds: negative, indifferent, and positive. Next, we employed data mining-based methods, including multilayer perceptron neural networks, random forest, and random tree algorithms. These helped identify essential variables affecting ranchers’ attitudes. The results showed that several factors contribute to the ranchers’ philosophy, with the number of sheep sold in the past year and the total sheep ownership being the most significant ones. Comparing statistical evaluation criteria, we found that the random tree algorithm outperformed other methods in predicting and classifying livestock farmers, achieving a prediction accuracy rate of 86% for a sample of 100 farmers. Based on our findings, promoting training courses and raising awareness about the benefits of breeding new sheep breeds, along with providing facilities and credits based on economic conditions, can foster a positive attitude among herders. Increasing the number of sheep owned and improving marketing strategies can further enhance this positive outlook. Full article

Although cicadas have traditionally been considered pests of little or no importance, in recent decades, an increase in damages is being recorded in olive groves of southern Spain. New agricultural practices that affect soil management are behind it. During 2024, intensive sampling has been carried out in an organic grove with herbaceous cover (VC2), and in a second one with mixed vegetation cover (VC1, in which the crushed remains of the annual pruning are added). In both ecological groves, inventories of the vegetation have been carried out, as well as intensive sampling in the olive canopy, with the densities of oviposition injuries being recorded and compared with respect to conventional management (CONV). The objectives of this study are to compare the three managements based on the density of oviposition injuries, to determine the priority areas for cicadas’ oviposition within the trees; and to develop a sampling method to assess damage over large areas. The results show significant increases in the density of injuries in organic groves, with maximum values recorded in the olive grove with mixed cover. Oviposition injuries show an altitudinal gradient distribution, with maximum values in the lower zone of the trees. The factors involved are discussed. Full article

The Ramganga River basin, comprising three rivers, the Dhela, Dhandi, and Ramganga, plays a vital role in groundwater recharge, sustaining numerous industries, urban areas, and rural communities reliant on these rivers for daily activities. The study’s primary purpose was to analyze the groundwater quality in the context of potability, irrigation, and health risks to the local inhabitants of the Ramganga River basin. In 2021–2022, 52 samples (26 × 2) were collected from 13 locations in two different seasons, i.e., pre-monsoon and post-monsoon, and 20 physico-chemical and heavy metal and metalloids were analyzed using the standard protocols. The result shows that heavy metal and metalloids and metalloid concentrations of Zn (0.309–1.787 and 0.613–1.633); Fe (0.290–0.965 and 0.253–1.720), Cd (0.001–0.002 and 0.001–0.002); As (0.001–0.002 and 0.001–0.002), Cr (0.009–0.027 and 0.011–0.029), and Pb (−0.001–0.010 and 0.00–0.010) values in mg/L are present in both seasons. The groundwater quality index (GWQI), heavy metal pollution Index (HPI), and heavy metal evaluation index (HEI) were used to assess the water quality and metal pollution in the basin area. As per GWQI values, water quality lies from excellent water quality (41.639 and 43.091) to good water quality (56.326 and 53.902); as per HPI values, it shows good (29.51 and 30.03) to poor quality (60.26 and 59.75) and HEI values show the low-level contamination (1.03–2.57 and 1.13–3.37) of heavy metal and metalloids in both seasons. According to the potential health risk assessment, infants show low risk in pre-monsoon and low risk to medium post-monsoon, while children and adults show low risk to high risk in both seasons. From the health risk perspective, it shows that children and adults have more concerns about non-carcinogenic effects, so adequate remedial measures and treatment are required to avoid the groundwater quality of the Ramganga River basin.
